2007 Pathfinder goin nuts

[paulstuff71]

Hello , this pathfinder is goin crazy. So when I turn the key it does nothing, like the battery is dead, the red key blinks in the interments panel, the dome lights are dim , i can hear a slight hum as if the horn wants to blow in security mode but to weak. Have anybody experienced anything similar, what should I do?
Thank you

Sounds like your security alarm is going off with a weak battery. Maybe unhook the battery for a few minutes, then try jump starting.
